Fixed Vertical Ladder

• Roof hatches should be easily operated while retaining safe points of contact. For a rule of thumb we highly recommend 3 points of contact onto the ladder at all times.
• The size of the roof hatch should be at least 900 x 750 to offer enough headroom for the user.
• Ladder should be positioned opposite the hinge side so the lid is behind the user (size permitting) or to the side.
• Consideration must be given for external hand holds and handrails to offer further support for exiting and entering the roof void.

SHIPS Companionway ladder

• Roof hatches with a SHIPS ladder should provide a minimum headroom clearance of 1200 according to BS 5395.
• Single line hand rail must be included either side of the ladder
• The ladders are designed for use in the 65° to 75° range.
• Heights over 3 metres require an intermediate platform
• Consideration must be given for external hand holds and handrails to offer further support for exiting and entering the roof void.

ZIP Retractable ladder

• The ZIP ladder is to be mounted at the lowest point of the aperture
• A further 50mm must be allowed if it is to be used with a Jakdor access panel
• ZIP 4 – 7 ladders are available up to a height of 3.39m
• A bespoke ZIP 8 is available for heights above 2.5m and is povided with an integral wooden trap door. The ZIP8 allows top down operation.
• The minimum dimension for a ZIP ladder is 640mm without a ceiling panel or 740mm with a ceiling panel
• Wall mouned rungs if required have a minimum spacing of 220mm
